    I was having my project on Automatic Meter Reading. The part on the power meter really cause a big problem for me as measurement cant be taken easily although the hardware is well configured with LCD, however i still need to make a simple power consumption meter for my own using PIC.

    I'd asked my supervisor opinion, and he suggest me with PIC. Does anyone can provide me with a detailed circuits that may works? PIC act as a controller, whenever PIC sense 0V, it will not starts measuring, else it will and keeps accumulating the power consumptions (can be in voltage and current). I might needs some help and guidance from all the experts here.

    Thank you so much:)

    Use a step down transformer to isolate and drop the voltage to a measurable level. Use a current transformer to measure the current.
